TANK-HEATER.

SPECIFICATION formingpart of Letters Patent No. 593,055, dated November 2, 1897.

Application filed February 3, 1897 Serial No, 621,800. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE SILAS Lone, a citizen ofthe United States, residing atHinckley, in the county of De Kalb and State of Illinois, have invented certain new and useful Improvements in Tank-Heaters, of which the following is a specification.

My invention relates to improvements in tank-heaters-that is to say, heaters adapted for warming the water in tanks used forwatering stock or for cooking feed in same by setting the heater in the tank.

The objects of my invention are, first, to save heat 5 second, durability; third, to so arrange the different parts that it will be convenient in using the same.

The several parts composing my invention are fully described and explained in the specification, and shown in the accompanying drawings, in which- Figure l. is a horizontal view of a heater embodying my invention with covers H H removed and'looking downward into heater. Fig. 2 is a central vertical section of the heater, the plane of section being through the line 3 4, Fig. 1, plainly showing flame-spreader D. Fig. 3 is a central vertical section, the plane of section being through the line 1 2, Fig. 1. i is a top plan of covers for heater.

Similar letters refer to similar parts throughout the several views.

In the views, A is preferably a cylindrical oblong casing having watertight walls and bottom. It maybe made of boiler-plate and riveted or bolted together, or made of castiron and fines E and F united thereto by bolting or rivetingsame to body A. Said fines may be made of cast-iron or boiler-plate riveted or bolted together or galvanized iron soldered. together, or the heater may be cast in halves, one section representing thewall and bottom of A, E, and F, Fig. 1, then bolt or rivet the two halves together, though it is preferable to cast said flues with main body A, making the entire casing and bottom of A, E, and F one piece of cast-iron, with lugs cast thereon for the retention in place of flame-spreader D, large grate B, small grate O, and lugs P P, for fastening the heater down to the tank, as hereinafter explained. I provide for this heater suitable covers H H, which, while effective, are very simple, having hanward for convenience in replacing same,.

which has to be removed to clean ashes from under grates.

O O are lugs which large grate B and small grate 0 rest on and upon which the fire is built. Flame-spreader D is also held inplace by the longestof these lugs O O, as is seen in Fig. 2.

Lifting oh. covers H H and brushing off coals or fuel from small grate G onto large grate B, the small grate C may be removed from heater or turned up on its edge reclining on lug Y, when a bent poker may be inserted into the hole or eye at the top of flamespreader-D, which may then be removed from the heater, and the process of removing ashes from the heater may then be carried on, as shown in Fig. 3, after which the grate ,C and flame-spreader D may be replaced and the fire built, covers II II put on, when air, which is regulated by damper I, will pass downward through flue F, thence upward through grates B and O, thence over flame-spreader D,which has the top of its outer edge out down, allowing its center to be much higher, spreads the draft or fire so it comes in direct contact with walls of heater A as it passes over flamespreader D, thence down and into the entrance of fine E, on which there is a pipe G, out of which pass the products of combustion. It is evident that there is much more heat saved by the top of this flame-spreader D being higher in the center and bringing the flame in direct contact with wall of body A than if it were square across its top; This flame-spreader D rests on the bottom of the walls of body A (see Fig. 2) and completes the fire-box, it being slightly perforated to prevent warping, but not enough to admit of a draft through the same.

Flues E and F may be joined to body A at They may be round, octagon, or square,

though it is preferable they should be round. They may be any desired size, though it is preferable that the top of fines E and]? be respectively five and four inches in diameter, increasing in size toward the bottom of each one.

The stability of this heater is secured by having cast, bolted, or riveted onto body A lugs P 1?, through which pass rods J, which are screwed into the bottom of tank, as shown in Fig. 2.

It is a well-known fact that cool air descends. I therefore build flue F a suitable distance from main body A, so as to have said flue cool, when it will supply the fire with muchmore oxygen than if said flue were connected the entire length to wall of body A, whilewith flue E there is much heat saved by bringing the products of combustion down to the base of the heater, then out of said fluea v I am aware that prior to putting my invention into practice there have been 'many different kinds of heaters made and patented for warming'water in stock-tanks, and that apatent was granted to Henry L. Ferris, of Han vard, Illinois, June 18, 1895. I am not aware that this ora'ny other heater is like mine in retaining the heat and bringing it in so close contact with the water after leaving fire-box as mine.

- I therefore claim as new and desireto secure by Letters Patent-'- 1. In a tank-heater, the combination of the casing A having water-tight walls and bottom, covers H,- H, for said casing, provided with a stationary lug X and an adjustable lug L, draft-flue F provided with damper I attached to 'thew'all of the "casing near the bottom,

grates B and (3, lugs O for supporting said grates, smoke-flue E, and flame-spreader D interposed between the grates and the smokefiue, substantially as described.

2. in a tank-heater, the combination of the casing A having water-tight walls and bottom draft-flue F attached to the wall of the casin g near its bottom-covers H, H, for said casing, grates B and C, smoke-flue E, a removable flame spreader D interposed between the grates and the smoke-flue, and lugs 0, S and T for securing-the flame-spreader in position, substantially as described.

Signed at Hinckley, De Kalb county, Illinois, this 1st day of February, 1897.
